The 1975 Honda CB400F Super Sport, also known as the 400 Four, didn’t get a lot of love from the buying public when it was introduced in 1975. But it became a favorite among the café-racing crowd and is collectible today.
Here are 10 tidbits about the classic machine.
1. In March 1975, Cycle magazine said: “At 10,500 rpm, a siren-song comes shrieking out of the engine and muffler, and this music is the most captivating sound west of an MV Agusta 750.”
2. In 1973, following the introduction of its CB750 and CB500 four-cylinder models, Honda decided to miniaturize the concept with the CB350 Four, one of the smallest production four-cylinder motorcycles ever imported into the United States.
3. The CB350F was a brilliant four-cylinder technical exercise but it was heavy, expensive and no faster than the company's own 350cc twin. So for 1975, the CB350F became the CB400F Super Sport, with a displacement boost to 408cc.
4. While the 350 looked like a smaller CB750, the 400 had minimalist, cafe-racer looks, with low, narrow bars for its day, a six-speed transmission and a red zone that started at 10,000 rpm.
5. Instead of the 350s muted colors, the 400 came in bold red or blue. And it came with one of the first four-into-one exhaust systems Honda ever offered.
6. The 400F didn't own the small-displacement performance title in the mid-1970s. Yamahas two-stroke RD350 could still show Hondas four-stroke its taillight at the strip. But the 400 Four was in the hunt.
7. Still, none of that was enough to make the 400 a sales success. Although widely admired, and collectible to this day, the 400F only remained in Hondas lineup for three years.
8. The bike, weighing about 392 pounds with a gallon of gas, boasted a top speed of 103.8 mph.
9. It had electric and kick start, a tubular single downtube cradle frame, and an engine that pumped out 37 horsepower.
10. Stopping power was provided by a front hydraulic disc and rear expanding drum. The tires were 3.00 x 18 front and 3.50 x 18 rear.
